Objective To probe into the application of cooperative group learning to ICU clinical nursing teaching.Methods The"cooperative group learning"is applied to nursing teaching of 60 undergraduate nurses doing their clinical field work in ICU of our hospital from 2005 to 2007.Results 60 undergraduate nurses'ability to gain information,utilize resources,analyze and solve problems has been improved.Conclusion The application of cooperative group learning to ICU clinical nursing teaching has achieved noticeable results in that it can motivate the nurses and arouse their interest in learning,improve their oral ability,cultivate their critical thinking and innovation ability,thereby improve their comprehensive quality and clinical practical skills.

Objective To develop an instrument for measuring family relocation stress scale during patient transferred from ICU. And to provide evidence for ICU health care personnel to assess and deal with the family member′s relocation stress. Methods A draft scale was developed based on the result of related scale abroad, literature review and semi-structured interviews. Delphi method and Classical test theory were used in item selection. Results The degree of experts′ authority in two rounds′consultation were 0.83. The Kendall′s coordination coefficients of importance were 0.36, 0.36 (P<0.05) in dimension and 0.35, 0.37 (P<0.05) in item. Five items were deleted by the statistical analysis with pilot investigation. 6 dimensions (transfer anxiety, environmental changes, disease severity, nursing model changes, the safety of transfer, self-efficacy of care ability) and 20 items consisted the scale. The Cronbach α coefficient was 0.882. Exploratory factor analysis extracted 6 items, accumulated variance contribution rate was 72.226%. Confirmative factor analysis showed χ2/df=1.677, comparative fit index=0.936, Tucker-Lewis index=0.921, root mean square error of approximation=0.061. Conclusions The scale is based on abundant theoretical evidence and reasonable design, with satisfactory reliability and validity. It can be used as the evaluation tool for family relocation stress during patient transferred from ICU.

Objective: To explore the effect of ISBAR communication mode on the bed shift in severe patients. Methods: The "ISBAR Nursing Delivery Card near the Bed of Severe Diseases Medicine" was formulated. 100 cases of severe patients admitted from February 2018 to March 2018 were set up as control group by experimental research methods. 100 cases of severe patients admitted from April 2018 to May 2018 were set up as experimental group and non-random control was established. The patients in the experimental group were treated with ISBAR nursing shift card for bed shift, and the control group were treated with normal oral shift. Observe and compare the incidence of nurse shift problems, the score of nurse shift assessment scale and the nurse′s knowledge of the patient′s condition "ten know" score between the two groups. Results: The incidence of nurse shift problems dropped from 39.50% (79/200) of control group to 16.50% (33/200) of experimental group, which had a significant difference (χ²=42.938, P<0.01). The score of the nurse′s succession assessment table was increased from (57.80 ± 3.61) points of control group to (73.96 ± 2.33) points of experimental group, which had a significant difference (t=-26.10, P<0.05). The nurse′s knowledge of the patient′s condition "ten know" had been increased from (72.14±4.13) points of control group to (87.75±2.54) points of experimental group, which had a significant difference (t=-32.01, P<0.05). Conclusion The use of ISBAR communication mode for serious patients in the severe medical department can effectively reduce the incidence of nurse shift problems, effectively improve nurses 'satisfaction with shift and the degree of mastery of patients′ conditions, and the effect of shift is better.

Objective To explore the better humidification oxygen therapy for patients with artificial airway from weaning to extubation, ensure the best humidification effect, keep airway unobstructed,shorten tubulization time and reduce the incidence of infection. Methods A total of 133 patients with artificial airway during weaning from ventilation admitted from March to December in 2016 in intensive care unit of the Second Affiliated Hospital of Chongqing Medical University were included in the study.They were divided into the experimental group(69 patients)and the control group(64 patients) by random lottery form.The experimental group was given improved combination device(venturi,heated humidifier and ventilator tube)during oxygen therapy for humidification and heating, while the control group was treated with oxygen therapy in endotracheal tube and continuous wet micro-injection pump 0.45% sodium chloride method.The heart rate,respiratory rate,blood oxygen saturation,offline time with tube,offline failure rate,sputum viscosity,sputum scab formation,irritant cough and pulmonary infection were compared between the two groups. Results The heart rate,respiratory rate,blood oxygen saturation and offline time with tube in the experimental group were(80.50±7.07)times/min,(17.38±1.92)times/min, 0.98±0.01,and(1.58±1.06)days,and which were(88.50±3.07)times/min,(21.38±1.51)times/min,0.96± 0.01 and(3.00±1.09)days in the control group.The differences were statistically significant(t=2.268-4.782,P<0.05 or 0.01).The offline failure(2 cases),sputum scab formation(3 cases),irritant cough(4 cases) and pulmonary infection(4 cases) were less than 8 cases, 12 cases, 20 cases,12 cases in control group. The differences were statistically significant (χ2=4.652-14.545, P < 0.05 or 0.01). The sputum viscosity ofⅠ,ⅡandⅢwere 5 cases,52 cases and 12 cases in the experimental group,which were better than 13 cases,11 cases and 40 cases in the control group.The difference was statistically significant(Z=3.385, P < 0.01). Conclusions The improved oxygen therapy heated humidify strategy can not only achieve satisfactory humidification effect, but also improve the success rate of offline machines, shorten tubulization time,promote the comfort and tolerance of patients,and reduce the occurrence of infection.
